A New Model in the Calogero–Ruijsenaars Family

Communications in Mathematical Physics. 2015. Vol. 338. No. 2. P. 563-587.

Hamiltonian reduction is used to project a trivially integrable system on the Heisenberg double of SU(n; n), to obtain a system of Ruijsenaars type on a suitable quotient space. This system possesses BCn symmetry and is shown to be equivalent to the standard three-parameter BCn hyperbolic Sutherland model in the cotangent bundle limit.
